In codbehind page


protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataTable dt = new DataTable("tblTest");
DataRow dr;

dt.Columns.Add("Name", typeof(string));
dt.Columns.Add("Add1", typeof(string));

dt.Columns.Add("Add2", typeof(string));
dr = dt.NewRow();

dr["Name"] = "Neha";
dr["Add1"] = "Address1";

dr["Add2"] = "Add 2";
dt.Rows.Add(dr);

GridView1.DataSource = dt.DefaultView;
GridView1.DataBind();
}
}
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridViewRow row = (GridViewRow)(((Button)e.CommandSource).NamingContainer);
int index = row.RowIndex;
//((TextBox)GridView1.Rows[index].Cells[3].Controls[1])
string strName = ((TextBox)((Panel)GridView1.Rows[index].Cells[3].Controls[1]).Controls[1]).Text.ToString();
Response.Write(strName);
}






You can write the below code in case of "btnAddDetails_Click" but here u have to preserve index value.

protected void btnAddDetails_Click(object sender, EventArgs e)
{
string strName = ((TextBox)((Panel)GridView1.Rows[0].Cells[3].Controls[1]).Controls[1]).Text.ToString();
Response.Write(strName);
}



do Let me know if it worked

In wrote the same code in GridView1_RowCommand event, just included the RowIndex like this

GridViewRow row = (GridViewRow)(((Button)e.CommandSource).NamingContainer);
int index = row.RowIndex;
pnlCustomer= (Panel)gvDetails.Rows[index].FindControl("pnlCustomer");
txtCustName = (TextBox)pnlRequestPopUp.FindControl("txtCustName ");
